Can a radon problem be fixed?
Yes. The solution is simple and relatively inexpensive. However, the best solution depends on the size and nature of the radon risk. If the radon levels are low, ventilation and sealing of cracks on the floor may solve the problem. Other situations may require active mitigation measures. The “standard” active mitigation system, that usually involves soil depressurization, costs about $1000 to $2000 installed. Other systems may cost $3000.
